Unit 5- States of Consciousness (2-4%) Flashcards
Latent content
According to Freud, the underlying meaning of a dream (as distinct from its manifest content)
Activation-synthesis theory
Neural activity is random, and dreams are our brains trying to understand it.
Sleepwalking
Performing motor acts while sleeping and then not remembering when you awaken. Happens during deep sleep (NREM stage 3)
REM Rebound
The tendency for REM sleep to increase following REM sleep deprivation.
Hypnosis
An artificially induced trance state resembling sleep.
Psychoanalytic dream theory
the process of explaining the meaning of the way the unconscious thoughts and emotions are processed in the mind during sleep.
Manifest Content
According to Freud, the remembered story line of a dream (as distinct from its hidden or latent content)
Circadian Rhythms
Biological clock, regular body rhythms
Sleep
Periodic, natural loss of consciousness. Not the same as unconsciousness in coma or hibernation.
Effects of sleep deprivation
Hunger High stress Less productivity More mistakes Irritability Fatigue
REM Sleep
Dream sleep (vivid dreams)
Rapid eye movement sleep
Muscles are relaxed while other body systems are active
NREM Sleep
Non rapid eye movement sleep
Encompasses all stages of sleep except REM (Stages 1-4)
Consciousness
Awareness of ourselves and our environment.
Examples: States of Consciesness
Sleep, wake, altered states (drugs, daydreaming, hypnosis)
Electroencephalograph (EEG)
A machine that records rapid eye movement and brain wave patterns. It’s used to study sleep patterns.
Hypnagogic State
Occurs in stage 1 of sleep. It’s when your body may suddenly jerk or when your floating weightlessly. These sensations may later be converted into memories.
Stage 2 Sleep
Sleep spindles appear and you start to relax more deeply during this stage.
NREM Stage 3 Sleep
Your brain emits large, slow delta waves. You are hard to awaken during this stage. Bed wetting and sleep walking are most likely to occur in this stage.
Dreams
A sequence of images, emotions, and thoughts passing through a sleeping person’s mind. Dreams are notable for their hallucinatory imagery, discontinuities, and incongruities, and for the dreamer’s delusional acceptance of the content and later difficulties remembering it.
